| Abstract: | We point out in this paper that there is an intrinsic error in a method proposed in the monograph 2]for extracting rules from an inconsistent decision table by some decomposition technique and analyze the reasons resulting in this error. Then. we study and scrutinize the relationship between core attributes and reduets of the original inconsistent decision table and that of its consistent sub tables after decomposition. |

| Keywords: | decomposition of inconsistent decision tables reducts rule extraction |
